COVID-19 News Update

COVID19 Pandemic

At the time of writing, The U&M Group is largely closed, following guidelines issued by the UK Government and Public Health England to help play our part in minimising the potential spread of the virus.

Our offices are operating with a skeleton staff and reduced hours.

Key staff in all departments have laptops and mobile devices and are home working.

Whilst our site activity has largely ceased, we have retained a limited number of operatives to undertake any emergency call out work, temporary propping, security etc that may be required during this partial lockdown. Please contact us through info@underpin.com.

As the advice is in a constant state of flux, we will be actively monitoring the situation and will implement any updated advice or guidelines.

We would also wish you all well during these very sad and disruptive times.

Kind regards and stay safe

What Are the Different Types of Brick Around?

What Are the Different Types of Brick Around?

Although modern buildings can be constructed from a wide variety of materials, brick is the traditional material of choice in most parts of the UK. There’s something reassuring about a brick-build home, with its bond left clearly visible.

But is a brick simply a brick? Not at all.

Materials for Bricks

Clay is the most common material for bricks, but this can vary according to where it comes from. The most obvious difference is the colour, indicating the type of clay, which tends to reflect the part of the country it comes from. Broadly, red bricks are characteristic of the north, for instance, while London and the Home Counties are more likely to have yellow or cream bricks.

However, a number of other materials are available for bricks:

  • Sand lime bricks, consisting of a mixture of sand, fly ash and lime, make a smoother finish possible.
  • Fly ash clay bricks are made from a mixture of fly ash, cement, sand and water.
  • Concrete bricks are ideal to go immediately above and below a damp-proof course.

Ways of Making Bricks

Bricks can be manufactured in different ways, which affect how they’re best used. The main methods are:

  • Extruded or wire-cut bricks, where the clay is extruded into a column and wire-cut into individual bricks. This is usually done by machine, keeping costs down, and produces smooth bricks.
  • Soft mud bricks, where the clay is dropped into individual moulds, producing creased faces. This can be done either by machine or by hand, though of course handmade bricks tend to be more expensive.

Alternatively, you can reuse bricks from demolished properties, which will reduce the carbon footprint of your project.

Shapes of Brick

The most common shape is the facing brick, which is the one normally found in the brickwork of a straight wall. However, bricks need to be used for the angles and corners on a building, too, and specialist bricks are available to suit all of these.

For example, angle and cant bricks are used to create returns and chamfers, while coping or capping bricks cap freestanding walls. There are also channel bricks, used to form channels and gutters, and curved sector bricks can be used for chimneys, pillars or columns.

Hollow bricks, around a third the weight of normal ones, are suitable for partitions, while the perforations in airbricks help with the circulation of air. There are many other specialist bricks available, and they can be custom made for specific uses. You’re very welcome to get in touch with us to find out more about what’s available.
